7、 Logic of JMeter sending request

One 、 Multiple requests under the thread group , After getting the return value of the last request , Then trigger the next request

Under the same thread group ,2 A request , request A, And request B.

Logic ：

  Execute the request first A, request A Get the returned results , Just start to execute the request B.

test ：

I use spring boot Wrote two requests , request A And request B.

Interface A After receiving the request , sleep 3S Then return the result

Interface B After receiving the request , Return results immediately

package com.example.testjmeter.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import javax.servlet.http.HttpServletRequest;
import java.io.IOException;
import java.util.Map;
import java.util.stream.Collectors;

@RestController
public class MockController {



    @Autowired
    private HttpServletRequest request;


    @RequestMapping("/a")
    public String doMock() {
        System.out.println(" Server received A request ------");
        String RequestURI = request.getRequestURI();
        String response = " The server has finished processing A request ";
        try {
            Thread.sleep(3000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        System.out.println(response);

        return response ;

    }


    @RequestMapping("/b")
    public String doMock1() {
        System.out.println(" Server received B request ----");
        String RequestURI = request.getRequestURI();
        String response = " The server has finished processing B request ";
//        try {
//            Thread.sleep(2000);
//        } catch (InterruptedException e) {
//            e.printStackTrace();
//        }
        System.out.println(response);

        return response ;

    }




}

then jmeter Thread group ,1 concurrent , loop 1 Time , Then execute the script .

jmeter Result tree display , Do it first A request , It was made after the war B request .

  Check the return side processing ：

  although A Interface is very slow , But it's still done A Just received B request .

Two 、 A request , Multiple concurrent

for example , A request , Set up 10 concurrent , Then this 10 A request , Almost simultaneously .

test 1

Interface request ,C,10 concurrent ,

for the first time 1s Ten concurrent

The second, 10s Ten concurrent
